Objectives: Ischemia-reperfusion (IR) contributes to the development acute renal failure. Oxygen free radicals are involved in the pathophysiology of IR injury (IRI). This study was designed to investigate the effects of 5-aminosalicylic acid (5-ASA), which is known antioxidant agent, in IR-induced renal injury in rats.
Materials And Methods: Male Wistar albino rats were unilaterally nephrectomized and subjected to 45 min of renal pedicle occlusion followed by 24 h of reperfusion. 5-ASA (300 mg/kg, i.p) was administered prior to ischemia. After 24 h reperfusion, urine and blood samples were collected for the determination of creatinine (Cr) and nitric oxide (NO) levels, and renal samples were taken for the histological evaluation.
Results: Treatment with 5-ASA significantly decreased serum Cr and NO levels, also significantly increased urinary Cr level and decreased histopathological changes induced by IR.
Conclusion: Treatment with 5-ASA had a beneficial effect on renal IRI. These results may indicate that 5-ASA exerts nephroprotective effects in renal IRI.

Ulcerative colitis, a chronic inflammatory condition of the colon, requires precise and targeted treatment, and polysaccharides, with their pH responsiveness and biodegradability, offer an innovative approach for colon-specific drug delivery. This study aims to develop a highly precise drug delivery system with enhanced therapeutic and targeting efficiency for ulcerative colitis, focusing on the preparation, optimisation, and evaluation of dual cross-linked mesalamine-loaded sericin-pectin (DSPs) micro-beads. These beads utilise the pH-responsive and microflora biodegradability properties of polysaccharides for targeted colon delivery, employing the Response Surface Methodology.

The symptom of macroscopic or 'visible' haematuria can cause significant patient distress, largely due to its' potential association with urinary tract malignancy, infection or glomerular disease. This lesson from practice describes the case of a 19-year-old female patient for whom the cause of red/brown urinary discolouration was found to relate to a reaction between renally excreted mesalazine and domestic bleach in the toilet bowel. Recognition of this phenomenon in patients taking mesalazine for inflammatory colitis is important to minimise patient distress and unnecessary investigation for a urinary tract cause.

Background: Inflammatory bowel disease (IBD) occurs in up to 70%-80% of patients with primary sclerosing cholangitis (PSC). Oral vancomycin therapy (OVT) has been reported to be effective in the treatment of IBD associated with PSC (IBD-PSC).
Objectives: To examine the effectiveness and safety of OVT in the treatment of IBD-PSC by performing a systematic review and pooled analysis of the literature.

Background: The efficacy of 5-aminosalicylic acid (5-ASA) in combination with advanced therapies (ADTs), particularly ustekinumab (UST), for the treatment of inflammatory bowel disease (IBD) remains unclear.
Methods: This retrospective cohort analysis used data from the Medical Data Vision database, including patients with ulcerative colitis (UC) and Crohn's disease (CD) who had initiated UST therapy. Cumulative UST continuation rates and factors associated with UST failure were analyzed, and post hoc subgroup analyses based on prior ADT use were conducted.
